The Honda 24621-921-010 Shaft Bush is a genuine OEM replacement designed for B75, BF5, BF8, BF50, BF75, and BF100 portable and outboard motors. As a direct Honda OEM component, it is manufactured to the same specifications as the original part it replaces, ensuring a correct fit without guesswork. Honda supersedes parts across serial number breaks, so verify your motor's serial number against the fitment table before ordering to confirm this is the right bush for your unit.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this bush meets the original dimensional and material specifications required for correct shaft support in these outboard motors.
- Broad Outboard Fitment — compatible with B75, BF5, BF8, BF50, BF75, and BF100 Honda outboard motors, including both portable and full outboard motor variants.
- Serial Number Verification Advised — Honda updates parts at production breaks, so cross-reference your motor's serial number with the fitment table to ensure this is the correct bush for your specific unit.
- Shaft Integrity — a worn or damaged shaft bush allows unwanted movement and play at the shaft, which can lead to vibration, accelerated wear on surrounding components, and degraded steering or throttle response.
A shaft bush is a plain bearing that supports and locates a rotating or sliding shaft within the motor's housing, keeping it properly aligned under load. It reduces direct metal-to-metal contact between the shaft and its bore, controlling lateral play and helping the shaft move smoothly and consistently. When the bush wears out or becomes damaged, shaft movement becomes sloppy, placing additional stress on nearby components and causing noticeable vibration or sluggish control response in the motor.
